Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
a mechanical energy is a kind of energy
Mechanical energy is the combination of kinetic energy and potential energy.
The combination of rotational force and forward movement make it possible for the screwdriver to use mechanical advantage
A generator changes mechanical energy into electrical energy.
mechanical energy-electrical energy-mechanical energy
how do we convert wind energy into mechanical energy
